Validating a Clinical Prediction Rule to Guide Manual Therapy and Exercise for Neck Pain Relief
Purpose
Neck pain is a common issue that can lead to long-term disability and lost work time for many individuals. Despite numerous studies, finding effective treatment strategies has been challenging. One possible reason for this is that treatments may not have been tested on the specific groups of people who would benefit most. A method was developed to identify people with neck pain who are likely to see significant improvements from a manipulation technique used by physical therapists, called cervical spine thrust joint manipulation. The investigators believe that patients identified as likely responders to cervical spine manipulation will show greater improvements in disability. The investigators aim to test whether this method works with different patients and therapists across the country through a multicenter randomized clinical trial. In this study, 160 patients with primary complaints of neck pain will be enrolled from 9 clinical sites. Designed with stringent criteria for inclusion, this study is a testament to our commitment to participant safety and the effectiveness of the treatment. Participants will be randomly assigned to one of two groups: (1) one group will receive 2 sessions of cervical spine manipulation followed by 3 sessions of exercise, and (2) the other group will receive 2 sessions of gentle hands-on treatment followed by 3 sessions of exercise. The primary goal is to measure changes in disability 4 weeks after starting treatment, with follow-ups after one week, 4 weeks, 3 months, and 6 months to assess both immediate and long-term effects. By providing crucial data on the reliability of our method in identifying patients who will benefit most from cervical spine manipulation, this study has the potential to significantly enhance decision-making leading to rapid improvement. Results from this study will provide clearer guidelines on the optimal use of cervical spine manipulation, potentially revolutionizing the way patients recover from neck pain.

Detailed Description
This study's primary objective will examine whether a previously derived clinical prediction rule (CPR) exhibits validity for identifying a subgroup of patients who respond favorably to cervical thrust joint manipulation (C-TJM). The secondary objective will determine if patients who are positive on the derived CPR and receive C-TJM will exhibit reduced downstream healthcare costs. This multicenter randomized clinical trial will enroll 160 patients with primary complaints of neck pain. Participants will be randomized into two groups: (1) 2 sessions of C-TJM followed by 3 sessions of stretching and strengthening exercises, and (2) 2 sessions of low-grade mobilizations followed by 3 sessions of the same stretching and strengthening exercises. The primary outcome is the change in disability measured four weeks post-treatment, with pain as the secondary outcome. Follow-up assessments will occur at one week, 4 weeks, 3 months and 6 months to evaluate both short-term and long-term effects. The exact inclusion and exclusion criteria from the CPR derivation study will be used within this validation study to determine participant eligibility. Data will be collected using standardized self-report measures and physical examination, and statistical analyses will be performed using a linear mixed model with repeated measures. The investigators hypothesize that patients identified by the clinical prediction rule to benefit from C-TJM will show substantial improvements in disability and pain. This study will offer valuable insight into the effectiveness of C-TJM for neck pain. Successful validation of the clinical prediction rule could lead to more efficient and cost-effective patient care, potentially reducing the burden of neck pain on healthcare systems and improving patient outcomes. As PI, responsibilities include protocol development, training, data collection, analysis, manuscript development and dissemination of findings.
